Displaying A Waveform On The Screen - YOKOGAWA DL7440 Operation Manual

Displaying a Waveform on the Screen

This section explains how to perform convenient, basic setting initialization and autosetup when you want to display
common repeating waveforms such as sine waves and square waves.
The procedure below restores the settings that are controlled using the front panel keys to their factory default values.
If this is your first time to use the instrument the procedure is not necessary, but performing the procedure now will
help you remember it for future reference. This initialization procedure is also useful when reentering settings to
match the input signal.
1
SETUP
You can automatically enter vertical axis, horizontal axis, and trigger settings according to the input signal. This
function is useful when you just want to quickly display the signal in order to determine what kind of signal it is and
what sort of settings might be required to measure it.

• After initialization, display for all channels is turned
ON, and the instrument enters START status.
• Items that are not subject to initialization using the
soft key procedure are the following.
The date/time setting, communication settings,
stored settings, the language setting, and the
SCSI ID setting.
To initialize all settings but the date/time setting,
perform the procedure below. Note that settings
cannot be restored after this procedure.

Auto setup executes.
To restore the settings prior to auto setup,
press this soft key.
• When you execute auto setup, only the display of
the channel on which the signal is being input is
ON.
• The waveforms on which auto setup can be
performed must have the following properties:
Frequency: approximately 50 Hz or higher
Absolute value of input voltage: max. value of 20
mV (1:1) or more
Type: repeating wave (non-complex)
